A new report is raising important questions about why Instacart prices vary for shoppers who select the same groceries from the same store. A collaborative study from Consumer Reports, Groundwork Collaborative, and More Perfect Union has uncovered significant inconsistencies in how Instacart displays pricing. Although many users assume digital grocery platforms show uniform prices, the findings suggest a more complex reality.
To understand how widespread the issue might be, researchers tested the app across multiple cities and dozens of shoppers. What they found highlights a hidden layer of variability that many consumers have likely never noticed.
Why Instacart Prices Vary According to the Study
The research team enrolled 437 participants across four cities. Each shopper added the same list of grocery items from the same store location in the Instacart app. Even though all conditions were identical, nearly 75 percent of the items appeared with more than one price.
Some products displayed up to five different prices. The average gap between the lowest and highest cost was around 13 percent, while the most dramatic example reached a 23 percent difference. These wide variations, even under controlled conditions, illustrate one of the clearest explanations for why Instacart prices vary so noticeably.
The results reveal that two people shopping for the same product may be presented with very different totals.
How Instacart Explains Why Instacart Prices Vary
When asked about the findings, Instacart said that the variations were part of short-term pricing tests conducted by a limited number of retail partners. According to the company, these tests resemble traditional in-store pricing experiments that help retailers better understand how customers respond to different price points.
Instacart stressed several points:
- the tests are random,
- they are not based on demographic information, and
- they do not qualify as dynamic pricing because they ignore supply-and-demand changes.
Instead, Instacart argued that the tests allow retailers to identify ways to keep essential items affordable. However, shoppers who encounter inconsistent totals may feel confused or misled, especially if they expect digital marketplaces to be transparent and stable.
Where Instacart Price Variation Appeared in the Study
Most discrepancies appeared at Safeway and Target locations. Both chains showed similar patterns during the study. However, Target clarified that it does not control prices shown on Instacart. In fact, the company said it is not affiliated with Instacart’s pricing decisions on the platform.
Instacart, meanwhile, told the New York Times that it had been evaluating different methods to cover operational costs at the time of the study. It also said pricing tests for Target stores have since been discontinued.
This separation between retailer markups and platform-driven pricing tests makes it difficult for shoppers to understand why Instacart prices vary across identical carts.
Instacart’s Response to Why Instacart Prices Vary
Following the study, Instacart published a blog post aiming to explain how these tests fit into its broader goals. The company suggested that experiments indicating higher prices are intended to help retailers lower prices long-term. It also highlighted its commitment to making groceries more accessible and affordable.
Despite these explanations, many consumers remain skeptical. Price opacity often erodes trust, especially when differences reach double-digit percentages. For users who rely on delivery apps as a primary shopping method, unclear pricing can create frustration and reduce confidence in the platform.
Why Instacart Prices Vary and What It Means for Shoppers
The study sheds new light on why Instacart prices vary even between users browsing the same store. Online grocery shopping offers convenience, but it can also introduce hidden pricing layers that customers may not expect. Because of this, shoppers may unknowingly pay more than others for identical items.
As digital grocery platforms continue to grow, transparency will likely become a more pressing issue. Users want predictable pricing, and retailers want flexibility to test cost strategies. Balancing both will be essential as the sector matures.
The Bigger Picture of Why Instacart Prices Vary
Ultimately, these findings show that Instacart’s pricing model is more fluid than many people realize. While the company argues that tests help retailers understand customer behavior, the inconsistent experience raises broader questions about fairness and communication.
As shoppers increasingly depend on delivery apps, clearer explanations of how prices are set—and why they differ—will be crucial for maintaining trust.
